Lord Cameron of Lochiel (Con)

My Lords, I thank my noble friend Lady Neville-Rolfe for tabling this amendment and all noble Lords who have spoken in this debate. I also express my thanks for the diligent work of the Joint Committee on the National Security Strategy. Its report into the vulnerabilities of our undersea cables is a brilliant piece of work and makes for sobering reading. As the noble Lord, Lord Cromwell, said, these are perilous times and there never has been a more important time to consider the measure proposed, given that cables are the invisible backbone of much of our economy, security and everyday life. As we have heard, they carry the vast majority of international data traffic, underpin financial transactions, connect critical services and link the UK to our international partners. The committee’s report underlined that while the UK has plenty of cable routes and good repair processes for what it phrased as “business-as-usual breakages”, there are distinct vulnerabilities particularly where multiple cables cluster, or connect to key landing stations, and in the links servicing our outlying islands. I represented the Highlands and Islands region in the Scottish Parliament for eight years or so, and that last point is very real to me on a personal level because these are not abstract concerns. They are very real. Damage to a cable connecting the Shetland Islands in 2022 disrupted mobile, landline and payment services for days. As we have heard, despite these vulnerabilities, the legal framework has not kept pace with the security environment. The principal instrument remains the Submarine Telegraph Act 1885. The deterrent effect of criminal sanctions matters. As the committee observed, the UK cannot simply assume that hostile actors would refrain from targeting these cables in a future crisis, and the Government have to be prepared for the reality that hostile states or proxy actors may exploit these vulnerabilities deliberately. In conclusion, I add that increasing penalties is certainly not the only measure the Government should be taking. The threats we face are far more wide ranging than simple criminality. There is a need for a whole of government approach to protecting critical infrastructure such as submarine telecommunications—that would involve the MoD, DBT, DESNZ and the Home Office. But this amendment is a start, and I hope that the Minister will listen and take action.
